Last week Tesla unveiled its electric Semi to great fanfare. The four-motor truck was announced with a 500-mile range and some self-driving capabilities. What Elon Musk failed to provide was a price. Now that’s changed: the regular versions of the 300-mile and the 500-mile trucks will cost $150,000 and $180,000 each. There is also a "Founders Series" of the trucks, which will cost $200,000 per truck. Tesla says the prices are "expected" leaving the company some wiggle room on the final pricing.

If those prices and specs stick then Tesla has a potentially disruptive offering with Semi. Most long-haul diesel trucks are priced around $120,000 and cost tens of thousands of dollars to operate each year. Tesla claims its all-electric Semi will provide more than $200,000 in fuel savings alone over the lifespan of the truck.
